Question

Which can be used as a monomer in a polymerisation reaction?

विकल्प

• C₂H₆

• C₂H₄

• CH₃Cl

• all of these

Answer 1

C₂H₄

Explanation:

A monomer used in polymerisation should generally contain a double bond or triple bond so that small molecules can join together to form polymers.
Ethene (C₂H₄) contains a double bond; it undergoes addition polymerisation to form polyethene. Ethane (C₂H₆) and chloromethane (CH₃Cl) do not undergo such polymerisation easily.
